Ultrasonic sound is of a frequency that is above our hearing (>20kHz).

The question asks for applications.
They are numerous but include cleaning (by cavitation in a liquid in which the work-piece is suspended), certain types of welding / soldering, crack detection in welds, encouraging certain chemical or physical reactions...
Medically, ultrasound is used for diagnostic imaging such as of the foetus, and the destruction of "stones".
Communication is at speed of sound. Signal attenuation. Noise of signal travelling through air.
Cal Poly Pomona College of Engineering's motto is 'Application of Knowledge'.
it reveals the nature of engineering student and the more important is application..... myself the most interesting scene is the baby delivery scene because that scene shows the application of engineering student in various ways
Synopsys has R/D as well as Application Engineering teams in Hyderabad. You see almost equal number of staff at banglaore and hyderabad.
Bionics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. In medicine, this means the replacement or enhancement of organs or other body parts by mechanical versions.
Ultrasonic waves fall outside the traditional electromagnetic spectrum range, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Ultrasonic waves are mechanical waves that propagate through a medium by means of compression and rarefaction of the material.
ultrasonic wave is sound frequency
An ultrasonic wave is a sound pressure wave that has a very high frequency. The frequency is higher that what humans can hear.
Radar is based on Microwave and detects the change in dielectric constant where as Ultrasonic is based on Sound Wave at high frequency (Ultrasonic Wave) and detects change in density of medium. Based on performance and accuracy Radar is a better solution than Ultrasonic. However for lower range liquid application ultrasonic is a cost effective solution. hope this is useful for you!
No ultrasonic waves are not a form of electromagnetic wave. Ultrasonic waves are nothing more than high frequency sound waves. They can be made with a suitable speaker or transducer.
The velocity of ultrasonic waves in kerosene is approximately 1,470 m/s.

Ultrasonic means 'faster than sound'. This means no sound wave can be faster than sound.
Yes.
no Because ultrasonic sound waves are not audible and it is not possible to create that much loudness in normal speakers.
Infrasonic waves are waves which are below humans hearing range while ultrasonic waves are waves which human beings can hear. Example-bat,dog etc and human beings (respectively)
It will never reach the moon. Being a sound wave, it requires a material medium in which to propagate.Virtually the entire distance between earth and moon is totally devoid of any material substance through whichsound may travel.
